/**
 * Represents a call log event interaction, wrapping the columns in
 * {@link android.provider.CallLog.Calls}.
 *
 * This class does not return log entries related to voicemail or SIP calls. Additionally,
 * this class ignores number presentation. Number presentation affects how to identify phone
 * numbers. Since, we already know the identity of the phone number owner we can ignore number
 * presentation.
 *
 * As a result of ignoring voicemail and number presentation, we don't need to worry about API
 * version.
